The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the urban area of Guilin City, Guangxi Province are as follows: food waste 47.94%, paper 18.64%, rubber 17.98%, textile (fiber) 5%, wood and bamboo 4.11%, ash and soil 0.7%, brick, tile, and ceramics 0.91%, glass 2.39%, metals 1.11%, and other 1.23%. The moisture content is 53.52%, higher calorific value of 7623.94 kJ/kg, and lower calorific value of 5693. 85 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for individual specific wastes such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. Each kg of this waste will produce 0.205 kg of slag and 0. The fly ash and slag, after precious metal recovery, are landfilled. The fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%; the waste heat supply process does not involve the conversion of different forms of heat and energy, so its heat efficiency is higher, with an average of 64%; through the comprehensive waste heat power generation process and direct heat supply process, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating.
